Liz Ritchie obtained her Ph.D. from Monash University, Melbourne, Australia. She is an Associate Professor in the School of Science, and is the Associate Dean for Education, at UNSW Canberra (located at ADFA), Australia. A/Prof. Ritchie’s broad research interests are tropical cyclones, tropical meteorology, extreme weather and climate impacts on societies.

For Future Research Students:

*** PhD scholarship top-up opportunity *** A project is available with CSIRO examining the microphysical structure of tropical convection using new microsat high spatial and spectral resolution observations in tropical cyclones and organised (Hector) thunderstorms. If interested, contact me at e.ritchie@adfa.edu.au.

Ph.D. scholarships of $35,000 (AUD) are available for high-achieving students (H1/High Distinction in their UG program and/or have completed a Masters by Research) in tropical cyclones, climate, societal impacts, remote sensing, and meteorological modelling under A/Prof Ritchie's supervision. if you are interested contact me at e.ritchie@adfa.edu.au.

Research: Physical understanding, estimation, and prediction of tropical cyclogenesis, tropical cyclone structure and intensity change, the extratropical transition of tropical cyclones and their downstream impacts, and tropical cyclone landfall impacts on natural environments and societies. Climate and environmental impacts on extreme weather behaviour. Weather Phenomena. Tropical cyclone storm surge and sedimentation from fresh-water inundation.

Applied Research Areas: Remote sensing detection, estimation, and prediction of tropical cyclones and other extreme weather. 

Professional Engagement: A/Prof. Ritchie is an editor of Weather and Forecasting and former editor of the Monthly Weather Review. She is a member of the World Meteorological Organization's (WMO) Working Group on Tropical Cyclones and the Australian Meteorological and Oceanographic Society's expert group on weather and weather prediction, has served on numerous NASA panels including Chair of the Senior Review, is a former Councillor of the American Meteorological Society, served on the U.S. Joint Hurricane Testbed Steering Committee, and has served in a number of leadership roles for the WMO International Workshop on Tropical Cyclones.
